Because the median is the value which is half-way along the list of values in size order. Another way of describing "half" is "divide by two".
Median is the middle number so you need to put them in order from the smallest to the largest and find the middle number. If this is two numbers you need to add them together and divide by two!
You need to add them all together in each group then divide by the amour of numbers. That will give you the average.
If you need to find a median between two numbers, pick one of them arbitrarily.
To find the median of an even number of values, you need to take the mean of the 2 middle numbers. Since there is only 2 numbers, take the mean to find the median. The median is (500 + 1M)/2 = 500250.
You would need to take repeated samples, find their median and then calculate the standard error of these values.
The median is the middle number. To find the median, you need to put all of the numbers in order. The one in the middle is the median. If there are two middle numbers, you divide the bigger number by the smaller number.
yes- it's a very easy way to do it

You add all the numbers up and then divide by the amount of numbers there are. e.g 2+4+6= 12, there are 3 numbers (2,4,6) therefore you divide 12 by 3, and you have 4, therefore 12 is the mean. The mode is the most common number, so if you have 3,3,4,5,5,5,5,6 and you need to find the mode, the mode is 5. The median is the middle number, so if you have 1,6,9,114,300 then 9 is the median as it is right in the middle.
To find the median you need to put all the numbers on a row, starting with the lowest number and ending with the highest. 1, 2, 4, 4, 8, 8, 8 Then you need to find the middle number. In this case it's 4. Therefore, the median is 4.
The median and mode of any number is the same number. The mode of 5 is 5, as is the median of 5. In other words, you need two or more numbers to determine the median and mode of those numbers.
To find the median of a group of numbers, you would need to find the middle number of the whole group. 1 6 8 9 7 2 1 Here is the (example) group of numbers that you will find the Median in. Simply cross out numbers on each side of the set of numbers until you are left with a reamaining number. This is your Median. 1 6 8 9 7 2 1
There is no direct relationship between the range and the median. So knowing that your median is 20 does not automatically give you the range. The median is just the middle value. That does not tell you what the first and last values are, which is what you need to know to find the range. The median of 19, 20 and 21 is 20, and the range is 2. The median of 4, 20 and 79 is also 20, but the range is 75. The median of 8, 16, 17, 23, 50 and 320 is also 20, but the range is 312. So, as you can see, the Median in no way can tell you what the range will be. You need to know what all of the numbers are, or at least the lowest and highest to know the range.
